Element reduced to a line.

I have previously got the model to run previously with the same global mesh size and with out the mesh controls. Only difference between the old model and the new model is a new surface, but the new surface does not contain the element that reduces to a line.

I have tried making a new study but the problem persists.

Does anyone know what could be causing this problem?

Also when i go to adjust the mesh tolerance, it doesnt change after i meshed it and check mesh details. it always shows a default 0.9mm tolerance. why is this?

yea ive tried playing around with the tolerance but the tolerance value i set is not what solidworks meshes it to and just changes it back to the default setting for some reason.

this is what i got back from soldworks:

SymptomWhen running a static analysis with a mesh containing shell elements, this error message appears atthe beginning of the analysis.

ExplanationThe error message is displayed because the solver detected one or more very, very sliver shellelements. This can happen if you have surfaces that have knife edges and sliver faces. The reasonbeing that based on the mesh size that you are using, one or several elements with a very highaspect ratio could have formed on these geometric entities. The area of such elements is almostzero.

SolutionTo get around the issue, you can do this:1. First plot the aspect ratio of the entire mesh. You can do this by right clicking on the meshand selecting Create Mesh Plot.2. Then select Aspect ratio and click OK to generate the plot.3. Identify the regions that have elements with a very high aspect ratio.4. Apply mesh controls to these regions.5. Re-mesh the model and run the analysis.The error message should go away.

You can also plot the mesh and do a List Selected on the mesh plot. This will list all the shellelements of the surface you will select. Since the element are sorted by number, you can easily findthe element which number is given in the message. You will then identify the area of the modelwhen the mesh causes a problem. then, either apply a mesh control or edit the geometry toimprove the quality of the mesh that will be generated.
